63-001: IA 1041 Fiduciary Return 63-001 (2025)
Iowa · Iowa DOR · Used for tax years 2025
The 2025 IA 1041 is Iowa’s fiduciary return for estates and trusts. It records estate or trust details, fiduciary information, residency status, and information about beneficiaries and composite credits.
What you'll need
Have the estate or trust’s name and FEIN, the fiduciary’s name and address, and the income, deduction, distribution, and payment information requested on the return. The form also asks for the decedent’s SSN, date of death, Iowa probate county, and probate number.
Depending on the entries you make, the form calls for:
- Federal Form 1041, Schedule B amounts to complete Iowa Schedule B.
- IA 102 with an amended return.
- Federal Schedule 4972 for Iowa lump sum tax.
- IA 130FID for the out-of-state tax credit.
- IA 148 for other nonrefundable or refundable tax credits.
- Federal Forms 1099 or supporting documentation for income tax withheld.
- Iowa Schedule CC for the composite and PTET credit.
- IA 4136 for the motor fuel tax credit.
- Statements for Iowa additions and deductions to ESBT income on Schedule E.

Paper-filed returns must be signed by hand or with a digital signature with a digital certificate. Stamped or typed signatures are not accepted.
For an amount due on line 48, pay electronically or submit payment with Iowa Tax Payment Voucher (96-048). The form does not provide e-filing instructions.
Common mistakes
- Using a typed or stamped signature. Paper returns require a handwritten signature or a digital signature with a digital certificate.
- Leaving out dollars and cents. The calculation pages specify that amounts must include dollars and cents.
- Missing the composite return warning. A “yes” answer to any of questions 1 through 4 on page 2 may mean there is a composite return requirement. The form directs you to the instructions.
- Forgetting IA 102 with an amended return. The amended-return checkbox says to include it.
- Entering a negative income distribution deduction. Schedule B, line 15 says to enter 0 if the result is zero or less.
Questions people ask
What tax rate does the 2025 form use on line 26?
Multiply Iowa taxable income on line 25 by 3.8% (.038).
How much is the personal exemption?
On line 32, enter $40 or the amount on line 31, whichever is smaller.
What is the difference between the power of attorney authorization and the tax disclosure designation?
The power of attorney authorization allows the listed representative to act for the estate before the Iowa Department of Revenue and receive confidential state tax information relevant to this return. The tax disclosure designation only allows the designee to receive the estate’s confidential state tax information about this return, not to represent the estate. Neither allows access to federal tax information.
What happens if I pay by check?
Paying by check authorizes the Iowa Department of Revenue to convert the check to a one-time electronic banking transaction.
